An .XOF file reflects the nonstandard nature of file extensions, commonly showing up either as a DirectX-style 3D file containing mesh and material data or as an OthBase XML Othello record holding moves and game information; the 3D file usually begins with "xof …" or appears binary, whereas the OthBase format opens as readable XML, so using a text editor is the quickest way to distinguish between the two.

When people say "XOF is a 3D graphics file," they’re saying it contains the necessary info for rendering 3D models in the legacy DirectX ecosystem, including meshes, normals, UV layouts, materials, frame hierarchies, and sometimes animation, stored as readable ASCII or binary, and because newer tools vary in compatibility, users often convert it to FBX/OBJ/GLTF, confirming its type by looking for an "xof …" header or 3D sections in a text editor.

To quickly tell what kind of .XOF file you have, start with basic quick checks: if the file came from a 3D pipeline, DirectX-era assets, or older game mods, it’s likely the 3D/X-file family, but if it came from Othello/OthBase tools or game databases, the XML variant is far more likely; opening it reveals more—clean XML with tags like `<?xml ...?>` means the OthBase format, while an opening header starting with `xof` or terms such as Mesh or Material, or binary noise with "xof" at the top, indicates the 3D type, and these hints usually settle the question quickly.

When we say "XOF is a 3D graphics file," we mean it contains structured information about a 3D object rather than a simple raster image, and historically it aligned with DirectX’s X-file format by packaging vertex/triangle meshes, shading normals, UV mapping data, and material attributes including color, shininess, transparency, and texture filename links.

Depending on the export format, it can also hold grouping and transform data and sometimes animation, and it may come in a text variant—where keywords are visible in a text editor—or a binary variant, which looks garbled while still representing the same 3D-building information To read more info on XOF file technical details have a look at our web site. .
